Although the basics of the story are the same, and most of the background info follows the official story, these animations are not considered canon to the LEGO Bionicle storyline. For example, according to the original story, the Toa Inika heroes arrived on the island a long time after the Piraka, and they had to race to get the Mask of Life. Whereas in these animations, the Toa have been on the island from the get-go, guarding the mask and building traps for the Piraka.
Two segments were deleted from the first episode (Vezok electrocuting the Le-Matoran captive and Zaktan swatting away a Ta-Matoran slave), likely because they were considered too violent.
Although the toy figure he is based on is colored gunmetal gray, Hewkii is for some reason colored brown in these animations. The toy was most likely originally meant to be brown but was changed due to brown action figures selling badly.
